Letters Patent No. 91,025, dated June 8, 1869.

IMPROVEMENT IN MACHINES FOR MAKING- PAPER BOXES.

The Schedule referred to in these Letters Patent and making part ci the same.

To all whom Iit may concern.:

Bc it known that we, Joux M. l). KeA'rING and THOMAS V. WArMoU'rn, of the city, county, and State of New York, have invented certain new and uscful .improvements in Machines for Making laper Match- Boxes, Envelopes, dto.; and we do hereby declare the following to be a clear and exact description of the same, reference being had to the accompanying drawings, tigures, and letters of reference thereon, making part of this specification.

Of the said drawings- Figure 1 is a perspective 4view of a machine embodying our improvements.

Figure 2 is a top view of the plate B.

Figure 3 is a side view elevation of a portion of machine.

Figures 4 and :'i are views of the die which forms up the blank.

Figures 6 and 7 show a paper-blank and a box.

Similar letters of reference indicate like parts in all the drawings.

Our invention consists- First, in the combination, with a plunger, of a die, constructed with the grooves and inclines shown so as to fold, lap, and unite the previously-cut and gunnned blanks, as they are forced through the die by the plunger.

Second, in thc employment and use of receivingboxes upon au endless belt, so constructed as to receive, hold, and convey the boxes for thc successive operations of gummiug and sanding.

Third, in the combination, with the receiving-boxes, endless belt, gum-fountain, and sand-box, of a lifter for forcing the sand into contact with the bottom of cach box.

Fourth, in constructing the sand-box of flexible material.

Fifth, in the combination, with the receiving-boxes and endless belt, of a plunger for discharging the paper boxes from the receiving-boxes.

To enable. others skilled in the art to inakeand usc our invention, we will describe the construction and operation of the saine.

Secured to a proper bed arc thc uprights A A, of the ti'amc, which are bolted together in any proper manner, and in the centre of this trame is a main shaft, G, which is the prime mover of all the parts.

rlo the upper part of the frame A, is secured a box, in which a bar, H, reciprocates, and by means of brackets lz and t, carries the plunger I and guunnersjj.

The lower end of this reciprocating bar H, is forked, andy straddlcs the main shaft O, and it receives its Ythe ,motion from a roll on a stud attached thereto, and the cam E.

On the main shaft C, is a cani, F, which, by means of a lever, d, secured to a rock-shaft, L, and a lever.

'Uma e mL/M M/a.,

P, reciprocates the nippers 1.', which slide in grooves i i', on thc top plate B of the machine.

On the ina-in shaft C, is a cam, g, on the inside of t-hc frame A, and directly back of the cam F, which operates a lever, m', which has its fulcrinn on the shaft L, and by a connecting-rod a', connects with a short lever, l1', pivoted on the shaft M, which lever carries a ratchet-ringer, which, in conjunction with a ratchet-wheel, e, on the shaft, rotates the shaft, and consequently the endless belt N', bynleans of a square arbor secured to the shaft, which square arbor receives a quarter revolution at each revolution of the main shaft C.

On the niain shaft C, is another cam, G, which, by means of a stud, operates the lever j, and through the medium of a connecting-rod and elbow-lever (l, reciprocates a slide, 1)which cfu-ries a gumming-roller, n. These cams are all of such shape as to give the required motion to the working-parts, and arc all reacted upon by coil-wire springs.

'lhe lever l), which is secured on the shaft L, has an elbow, x, and as it is vibrated, carries a lifter, w, to bring the sand-box U in contact with the ends of the boxes, as they pass over the sand-box. Upon this lever is an arm, projecting downward, andA this arrn connects with a rocking levcr, z, which is counccted with a bracket, secured to a frame by a rod. The upper end of this vibrating lever engages with the plunger df, which discharges the paper boxes from the receiving-boxes. This dischargingplunger slides in a proper groove or grooves, on a plate scoured to the frame of the machine.

On the upper side of this plate is scoured the reservoir or fountain, V, for gumming the ends ofthe boxes. This reservoir is provided with a roll, e', which, by the friction of the endless belt, rotates intermittently, and, as the ends of the paper boxes which project through the Vreceiving-bores are drawn over this roll, a sufiicient quantity is applied to the end of the box for causingr the sand to adhere.

The distributing-roller o, which supplies the gumming-rollcr n, is driven by a belt, or cord, passing from the pulley C on the main shaft, to the pulley g', on the shaft ofthe distributing-roller.

The drum K, over which the endless belt passes, is secured in brackets lr u, which are bolted to the frame. The brackets are slot-ted longitudinally, so that the endless belt can be kept suiiciently taut.

The construction of the nippel-s and the operative mechanism will be readily understood from an inspection of the drawing, figs. 2 and 3.

The sp1ing-arms k k, are secured to a shaft, which has its bearings in brackets attached to the slide h', and the arms k 7.'. are held to the plate by a spring on the shaft arranged for the purpose.

The operation of the machine will be as follows:

"lhe reservoirs V W being supplied with gum, and the sand-box U in proper condition, the pile of paperlanks S, of the shape shown in tig. 6, is laid in the box r, on the plate a.

The shaft O is made to revolve by proper mechanism, and while the plunger I is at its highest point and at rest, the roll n, which has been in contact with the distributing-roller o, in the gum-reservoir W, passes back and forth under the pieces jj, on the rods, and coats them with the proper supplyof gum. The pieces jj then descend upon the pile of blanks-the coilspring upon the rods adjusting the rods to the thickness of the pile of blanks-and lift the blanks to the plate b.

,Y The' nippers k lt now come forward, and by means of the pin in the lever Z, travelling upon the incline j', open so as to pass over the blank, and as the pin drops over the incline, the nippers clamp the blank' to the inclined projection n', and, as the nipper-plate h recedes, the blank is carried forward so that the endl'laps T', will be directly under the plunger I. The plunger now descends, doubles the blank into the die, and in the descent passes the blank down the inclines o 0,g. 5, in the die, which fold the inside flaps, while the outside aps aregradually folded in the grooves k 7:', in the die, and as the plunger dcscends, the gurnined flaps are lapped to the flaps p p,g. 6, and by pressure in the lower part of the die, are inade to adhere firmly together, and the plunger still descending, forces the folded box into the receiving-boxes. The plunger is withdrawn and the op eration repeated.

The paper box in the receiving-box is then carried forward by the endless belt, and the end of the paper box which projects through the receiving-box, drags over the gum-roller e', which coats it with guru, and when directly over the sand-box, the' Inter w is raised,

and the sandin the box is brought in contact with the end of the box, and a suiicient quantity will adhere theretovfor striking the match. The box is then carried forward onthe endless belt until punched out by the discharging-plunger d.

The receiving-boxes N are secured to the perforated endless belt, N', in any proper manner, and they are bell-mouthed, so that the plunger and paper box will readily enter them.

Having thus fully described our invention,

What we claim, and desire to secure by Letters Patent, is-

1. The combination, with the plunger I, of the double die T, constructed with grooves and inclines at both sides, as shown, so as to double-lap and unite the previously-cut and gumlned blanks as they are forcedthrough the die by the plunger, substantially as described and specified.

2. The employment and use of the receiving-boxes upon the endless belt, so constructed as to receive, hold, and convey the paper boxes for the successive operations of gumming and sanding the ends of the saine, substantially as described and specified.

3. The combination, with the receiving-boxes and endless belt, the gulli-fountain and sand-box, of the lifter for forcing the sand into contact with the end of each box, substantially as described and specified.

4. Constructing the sand-box of flexible material, substantially as described and specified.

5. `'Thecombination, with the .receiving-boxes and endless belt, of the plunger for automatically discharging the paper boxes fromthe receiving-boxes, substantially as described and specified.
